This CGC 8.5 copy of Detective Comics #377 (July 1968) features a memorable Riddler appearance in a Gardner Fox story with art by Irv Novick, Frank Springer, Sid Greene, and Murphy Anderson. The cover shows Batman imprisoned while Robin and the Riddler stand triumphantly outside — a striking reversal of roles that makes this issue a standout in Silver Age Batman history. With cream to off‑white pages and vibrant colors, this copy offers strong collector appeal and classic DC charm.
